Assertion
The setting sun appears to be red.
The setting sun appears to be red.

Answer 1

Correct option is C. Assertion is correct but Reason is incorrect
The sun and its surroundings appear red during sunset or sunrise because of the scattering of light. During sunrise or sunset, the sun is tangential to the earth surface with cause more scattering and not only scatter blue light but also red so the sky appears red. The amount of scattered light is inversely proportional to the wavelength of light.
